1.1 本试验方法包括在低温条件下评估某些汽车设备中柴油的可过滤性。 1.2 以国际单位制表示的值应视为标准值。本标准不包括其他测量单位。 1.3 警告- 汞已被许多监管机构指定为可导致严重医疗问题的危险物质。汞或其蒸汽已被证明对健康有害，对材料具有腐蚀性。处理汞和含汞产品时应谨慎。有关更多信息，请参阅适用的产品安全数据表（SDS）。销售汞或汞的可能性- 当地或国家法律禁止含有产品或两者。用户必须确定其所在地销售的合法性。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 有关特定警告声明，请参阅 1.3 , 9.1 , 9.2.1 , 9.3 , 9.5 和 附件A1 . 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 低温流量试验结果表明了某些柴油车辆中试验燃料的低温流量性能（根据CRC第528号报告）。该试验方法特别适用于评估含流动改进剂添加剂的燃料。 5.2 试验方法可用于补充柴油低温性能的其他测量（根据试验方法 第97页 , 2500美元 和 第3117页 ).

1.1 This test method covers estimating the filterability of diesel fuels in some automotive equipment at low temperatures. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 Warning— Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 1.3 , 9.1 , 9.2.1 , 9.3 , 9.5 , and Annex A1 . 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 The Low Temperature Flow Test results are indicative of the low temperature flow performance of the test fuel in some diesel vehicles (according to CRC Report No. 528). The test method is especially useful for the evaluation of fuels containing flow improver additives. 5.2 The test method can be used to supplement other measurements of diesel fuel low temperature behavior (in accordance with Test Methods D97 , D2500 , and D3117 ).
